Georgia Hartzenberg


"I went into science because my ambition was to solve the mysteries of the universe. Knowing that I'm walking in the footsteps of the scientific greats is incredibly inspiring."

Profile picture of Georgia Hartzenberg

I am a young scientist with a keen interest in understanding the nature of the universe. I began my scientific career at the Queensland University of Technology (QUT), where I studied a Bachelor of Science. I majored in Physics, took minors in Astrophysics and Earth Science, and graduated with a Distinction. Shortly after completing my undergraduate degree, I was then accepted into my MPhil program at QUT, where I studied the physical processes of distant galaxy environments and evolution. Specifically, I used data from the FourStar Galaxy Evolution (ZFOURGE) survey, discovered new high density environment candidates across 2.0 ≤ z < 4.2 (or when the universe was approximately 3.2 to as young as 1.4 billion years old) and found that these environments appear to play a role in influencing early galaxy evolution. I am also the first postgraduate student and alumnus of the new QUT Astrophysics Research Group.

In addition to research, I enjoy sharing my work with both scientific and non-scientific communities via media and talks, teaching and supervising undergraduate students, and collaborating with supervisors and academics in external universities. Currently, I am a PhD Candidate in The University of Queensland's (UQ) Astrophysics Group, studying the chemical content/metallicity evolution of local and distant galaxies.
